Risk factors for thyroglossal duct remnants after Sistrunk procedure in a pediatric population.

To evaluate recurrence after surgery for thyroglossal duct cyst (TDC) we performed a retrospective chart review. Seventy four patients between 0.5 and 8.5 years of age presenting with a midline neck cyst underwent a Sistrunk procedure for a preoperative diagnosis of TDC. Fifty-seven had histologically confirmed TDC (mean age of the population: 4+/-1.5 years, mean follow-up: 6 years and 8 months). Recurrence occurred in 15% of the cases of histologically confirmed TDC. Four individual risk factors have been identified: number of infection before surgery [more than 2 episodes (P<0.05)]; preliminary surgical procedure (P<0.05); age [less than 2 years (P<0.05)] and multicystic lesion on histopathology (P<0.01). The two first factors being correlated, the risk of relapse might be lowered by a wide excision performed before any infection in children over 2 years.
